WILLIAM GOTTER WILSON, 0F BROOKLYN, NEW YORK.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented May 24, 1910.

Application filed April 19, 1909. Serial N 0. 490,976.

To all whom it may concern:

Be it known that I, WILLIAM COTTER VIL- SON, of Brooklyn, in the countyof Kings and State of New York, have invented certain new and usefulImprovements in Non- Refillable Bottles; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to whichit appertains tomake and use the same.

The object of this invention is to provide a non-refillable bottle fromwhich the contents may be readily discharged, without the possibility ofits being refilled unless the closure be destroyed. And a further objectis to locate all the parts of the closure within a capsule which isfixedly secured to a bot tle neck.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection. Fig. 2 is a view of the valve casing and its top detached. Fig.3 is an inverted view in perspective of the inclosing cap. Fig. 4 is aview of the removable screw cap.

Referring to the drawings, 1 designates a capsule which is cemented tothe exterior of a bottle neck and which at its upper end has a circularenlargement in the form of a band 2. Within the space inclosed by thisband is fitted the cone-like top 3 of a tubular valve casing 4, whichlatter at its lower end has an inwardly extending valve seat 5 for avalve 6. This valve has a cone-like end which is designed to fit againstseat 5, the remaining portion of the valve being tubular and open at theinner end. An air vent 7 is formed in that portion of the valve which isnormally in engagement with seat 5. When, however, the bottle isinverted the weight of the cone-end of the valve will cause it to fallfrom its seat and the liquid will freely flow from the bottle by reasonof the air admitted through vent 7 and the tubular portion of the valve.The cone-like top 3 of the valve casing is cemented within the top ofthe capsule, with a surrounding space between itself and band 2.

8 designates a cap, of slightly tapered formation, which at its lowerend fits in the space between band 2 and the top 3, and wherein it isheld by cement, or other suitable means. This cap has a perforateddiaphragm 9 and an externally threaded extension 10 formed, to one sideof its center, with an outlet opening 12. Between the top 3 and thediaphragm 9 is located a disk'13, of mica, celluloid, or other suitablematerial, which normally closes the outer end of valve casing 4. Whenthe bottle is inverted this disk will be prevented from closing theopenings in the diaphragm by a cross rod 13 located beneath thediaphragm. The opening 12 of the cap is normally closed by a smallersecondary cap 14 which is screwed on extension 10. This cap also carriesa disk 15 of mica, celluloid or the like, so that the outlet opening 12will be securely closed. WVhen the cap 14 is removed to discharge thecontents of the bottle the disk 15 may be removed before the secondarycap 14 is replaced, and thereafter when a portion of the contents is tobe emptied it is necessary to only turn cap 14 sufficiently to cause anopening 16 therein to coincide with opening 12.

Inpractice, the bottle may be filled before any part of the closure issecured thereto, but if desired the capsule 1, together with its band 2and the valve casing 4 at its top 3, may be cemented to the bottle neckbefore the bottle is filled. In this event valve 6 is dropped into placeafter the bottle is filled, and the disk 13 being positionedover theoutlet opening of the valve casing cap 8 is secured in place by cementor solder so as to prevent the parts from being separated other than byabsolute destruction. To discharge the contents the secondary cap 14 isremoved, or an opening may be punctured in disk 15 when openings 12 and16 are coincident, in which event the liquid may be discharged withouthaving to remove cap 14, and the seal may be formed by slightly turningsuch cap.

The advantages of my invention will be apparent to those skilled in theart, and foremost among these is the factthat it may be readily andeasily applied to various styles and forms of bottles.

I claim as my invention:

1. A bottle closure comprising a capsule designed to be permanentlysecured to the exterior of a bottle neck, a valve casing de pendingwithin said capsule and having a seat at its normally lower end, a valvefitted in said casing and having a tubular portion extending into thebottle and open at its lower end, said valve having a vent communicatingwith its tubular portion, a cap permanently secured to the upper end ofsaid capsule inclosing said valve casing and having an outlet, a disklocated Within the cap for normally closing the outlet from the Valvecasing, and means within the cap for preventing such disk frominterfering with c the outlet of the cap when the bottle is in- Verted.

2. The herein described bottle closure comprising a capsule designed tobe permasaid cap being permanently secured Within the upper end of saidcapsule and having an outlet opening and a perforated diaphragm, a diskbetween said valve casing and said diaphragm, and a secondary cap fornormally closing the outlet of the first mentioned cap.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
